Any help would be appreciated! I am considering doing an exchange semester at DTU this spring, but my internship ends 2 weeks into the semester. Is it feasible to arrive late to an exchange semester (I haven’t picked any courses with group projects or assessments early on).
I’m worried about getting my student id and health card, as well as visa rules.
It’s the only time in my degree that I could do exchange and I really want to do it, I’m from Australia and Denmark sounds so cool to live in.
Thanks, and any advice would be great:)
